NORMAN, Okla. - TCU right fielder Jake Duncan (Marshall, Texas/Marshall) tied the school and Conference USA records by belting three home runs, but it was not enough as the Horned Frogs fell to Oklahoma 13-6 Tuesday at L. Dale Mitchell Park. The loss was the third-straight for the Frogs, who dropped to 9-7 on the season.

After a scoreless first inning, Duncan put the Frogs on the board by driving the first pitch he saw in the second inning well over the 411 foot-mark in center field, giving TCU a 1-0 lead.

The Horned Frogs added another run in the second and three more in the third to push their advantage to 5-0. Duncan highlighted the third-inning outburst by connecting again on the first pitch for a two-run homer to right.

However, TCU's lead would disappear over the next two frames as Oklahoma (6-2) posted a run in the fourth and exploded for eight more in the fifth to take a 9-5 lead into the sixth.

Duncan saw two balls miss the strike zone as he led off the sixth, but blasted the first strike over the center field wall for his third round-tripper of the day, bringing the Frogs within three at 9-6.

That would be as close as TCU would get, however, as the Sooners tallied four more runs in the seventh as cruised to the victory.

OU reliever Austin Mix threw three strong innings, allowing just one run on four hits to pick up his first victory of the season. TCU hurler Ryan Grafe (Austin, Texas/Lanier) gave up eight runs on six hits and three walks in just two-thirds of an inning in falling to 1-1 on the campaign.

In all, Duncan went 3-for-4 with the three homers, three runs scored and four RBI in the record-tying performance. He is one of just eight players in the 108 seasons of Horned Frog baseball to hit three home runs in one game and the first since Chris Connally launched three versus Rice on May 14, 1998. He is also only the 20th player in Conference USA history to go deep three times in a contest.

TCU will look to end its longest losing skid of the season when it hosts former WAC-foe BYU for a three-game series at Lupton Stadium and Williams-Reilly Field. The first game of the set is slated for 6:30 p.m. Thursday.
